Question 1 POST_UTME_JOSEPH_AYO_BABALOLA_UNIVERSITY • 2019 • PHYSICS • objective

A parallel plate capacitor has plates of area $A$ and separation $d$. If a potential difference of $V$ is applied across the plates, calculate the capaci\tance $C$ u\sing the formula $C = \frac{epsilon_0 A}{d} left\( 1 - \frac{V^2}{2 epsilon_0 A V_0^2}\right \)$, where $V_0$ is the breakdown voltage of the dielectric material.

Answer Options

A. C = \frac{\epsilon_0 A}{d} \left\( 1 + \frac{V^2}{2 \epsilon_0 A V_0^2}\right \)
Correct Answer B. C = \frac{\epsilon_0 A}{d} \left\( 1 - \frac{V^2}{2 \epsilon_0 A V_0^2}\right \)
C. C = \frac{\epsilon_0 A}{d} \left\( 1 + \frac{V^2}{2 \epsilon_0 A V_0^2}\right \)
D. C = \frac{\epsilon_0 A}{d} \left\( 1 - \frac{V^2}{2 \epsilon_0 A V_0^2}\right \)
Correct Answer
B
Correct Option:
C = \frac{\epsilon_0 A}{d} \left\( 1 - \frac{V^2}{2 \epsilon_0 A V_0^2}\right \)
